hum, hum .... I don't even get where the problem is.

You have to send values in the range 0-255 which is exactly the unsigned char range,
unsigned char is usually the kind of data used to handle characters in C,
and by chance also the format of any adressed data (8 bit) for the 8052 (forgetting the DPTR trick)

So by transitivity

1) you are lucky
2) a char is just what you need
3) the 8052 is perfect for the job
